Background technology
Sulphur is the harmful element in the steel, produce high-quality steel grade especially specific use steel and the just necessary sulfur content that reduces in the steel of high added value steel grade.Along with steel market competition be growing more intense and the user to improving constantly that the steel end product quality requires, desulfurizing iron has become operation indispensable in the modern steel commercial production flow process.In numerous desulfurization methods, the desulfurizing iron preconditioning technique more and more is subjected to the favor of iron and steel enterprise with its good practicality, economy.Mechanical agitation desulfuration and blowing desulfurization are used widely in iron and steel metallurgical industry as two kinds of modal desulfurizing iron preprocess methods.
At present, extensively adopt the method for type approval test to carry out about the research of desulfurizing iron production Technology both at home and abroad, though type approval test research can reflect the influence relation of operating procedure parameter to desulfurized effect more intuitively, but owing to can't accurately measure to stirring and evenly mixing process in heterogeneous flow field and the molten bath in the hot-metal bottle, limit the quantitative examination of desulfurization dynamic conditions, influenced the further improvement of desulfurized effect.Simultaneously, owing to reasons such as type approval test expense height, test period are long, process stabilizing control difficulties, caused that tested number is big, data are many, low precision, not only influenced the reliability of test, the while also causes the waste of human and material resources, financial resources.
At above-mentioned deficiency, to improve the desulfurization dynamic conditions, improve the accuracy of result of study, reduction experimentation cost is target, the hydraulics physical simulation experiment device that some scholars have successively designed the different structure form has carried out modeling effort to molten iron mechanical agitation desulfuration and blowing desulfurization process, for example, the Liu Yan of Northeastern University etc. has designed a kind of desulfurization water mould experimental provision (Liu Yan etc., the water model experimental study of KR stirring technique, industrial furnace, the 29th the 1st phase of volume), with organic glass jar simulation ladle, tap water simulation molten iron, organic glass jar and the design that has the paddle of swivel nozzle have been carried out according to certain simulation ratio, the stable conductivity time with organic glass jar unique point is mixing time, by simulated experiment, study related process parameter in the magnesium base novel compound powder blowing desulfurization technology to the influence relation of melt tank mixing time, obtained nozzle location, structure and rotating speed of agitator, the law of regularity that structure etc. are improved the desulfurization dynamic conditions; The yellow group of Wuhan University Of Technology is newly with water simulation molten iron, visual organic glass jar simulation hot-metal bottle, designed molten iron spraying desulfurization spraying water mould experimental provision (Huang Qunxin according to certain simulation ratio, the molten iron spray magnesium sulfur removal technology of simulation blowing desulfurization is optimized water mould experimental study, the master of Wuhan University Of Technology thesis, in June, 2005), and with the stable conductivity time of organic glass jar unique point be mixing time, by simulated experiment, study related process parameter in the blowing desulfurization technology to the influence relation of melt tank mixing time, obtained position of lances, factors such as blowing gas flow are to the qualitative rule that influences of blowing desulfurization dynamic conditions; Iron and Steel Research Geueral Inst Wu Wei etc. has designed a kind of desulfurization water mould experimental provision (Wu Wei etc., pulse rotation stirring, blowing iron liquid new desulfurization process experimental study, China is metallurgical, the 16th the 1st phase of volume), with water simulation iron liquid, polytetrafluoroethylplastic plastic particle simulation desulfurization powder, pressurized air simulation winding-up carrier gas, carry out organic glass jar and the design that has the stirrer of spray gun according to certain simulation ratio, adopting the stable conductivity time of organic glass pot bottom unique point is mixing time, by simulated experiment, comparative study pulse rotation stirring, blowing iron liquid new desulfurization process and former mechanical agitation desulfuration technology to the melt tank mixing time, plastic grain is involved in the influence relation between the quantity of molten bath, obtained qualitative the influence rule of factor such as agitator speed in the new technology to the desulfurization dynamic conditions; Wuhan Iron and Steel Plant research institute Ceng Tong etc. has designed a kind of mechanical agitation desulfuration water mould experimental provision (Ceng Tong etc., hot-metal bottle KR mechanical agitation type desulfurization water mould experimental study and application, metallurgical information guide, 2006 the 3rd phases), with water simulation molten iron, polystyrene expansion plastic simulation desulfurizing agent, carried out the making of organic glass stirred pot and stainless steel stirrer according to certain simulation ratio, the degree of depth that reaches with plastic foam is a penetration depth, by simulated experiment, studied the influence relation of related process parameter in the mechanical agitation desulfuration technology, obtained agitator speed the plastic foam penetration depth, slip into the law of regularity that factor such as the degree of depth is improved the mechanical agitation desulfuration dynamic conditions.
According to report as seen, by above-mentioned analogue experiment installation, by the modeling effort to different desulfurizing iron technologies, though the law of regularity of part Study has certain directive function to the practical sulphur removal process modification, control still is apparent not enough to the sulfur removal technology optimum parameters.Physical simulation for blowing desulfurization technology: simple gas, liquid two-phase analog form can not represent complicated influencing each other between heterogeneous in the blowing desulfurization process truly in the molten bath, cause the distortion in physical simulation flow field, have influenced the accuracy of experimental result; Carry out the judgment mode of blowing desulfurization dynamic conditions with the mixing time of the stable conductivity of unique point in the molten bath,, cause experimental simulation result's remarkable deviation because the reaction of the solid-liquid interface of practical sulphur removal is completely different with electrolyte dissolution diffusion form.Physical simulation for mechanical agitation desulfuration technology: the amount of being involved in of simulation desulfurizing agent and its penetration depth in the molten bath can not reflect fully that stirrer causes physical simulation experiment relatively poor to the accuracy that technological parameter in the actual production instructs to the resultant effect that mixes of desulfurizing agent in the mechanical agitation desulfuration process.In addition, above-mentioned analogue experiment installation automaticity is lower, simulation process narrow range (experimental provision can only be simulated a kind of sulfur removal technology), defectives such as the experimental work amount is big, the artificial data picking rate is slow, working condition change difficulty have been caused, cause that the experimental provision utilization factor is low, labour intensity is big, data precision is low, influenced modeling effort result's accuracy.
